Dry laminating machine glue for the solvent type, are certainly toxic, but should also be specifically differentiated:
1, low-toxicity solvents, such as lipid solvents, ketones, etc.;
2, poisonous solvents, toluene, xylene, methanol, cyclohexanone, etc.;
3, high-toxicity solvents, benzene, carbon tetrachloride, etc.
Solvents: alkanes, olefins, alcohols, aldehydes, amines, esters, ethers, ketones, aromatic hydrocarbons, hydrogenated hydrocarbons, terpene hydrocarbons, halogenated hydrocarbons, heterocyclic compounds, nitrogen-containing compounds and sulfur-containing compounds and so on, most of the human body has a certain degree of toxicity. Specific toxicity is categorized as follows:
(1) solvents that damage nerves: such as primary alcohols (except methanol), ethers, aldehydes, ketones, some lipids, benzyl alcohols.
(2) Solvents that poison the lungs: such as methyl carboxylates, formic acid lipids.
(3) Solvents for blood poisoning: e.g. benzene and its derivatives, ethylene glycols.
(4) Solvents for liver, i.e. metabolic poisoning: e.g. halogenated hydrocarbons, etc., amino and nitro compounds of benzene.
(5) Renal poisoning of solvents: such as tetrachloroethane and ethylene glycol class.
(6) Reproductive toxicity of solvents: such as carbon disulfide, benzene and toluene.
(7) Tumor-causing solvents: such as benzidine to bladder cancer, chloromethyl ether to lung cancer, vinyl chloride to liver angiosarcoma.
